To all whom it mayco noem:

Be it known that I, CHARLES A. PURVIS, a citizen of the United States, and a resident of Versailles, in the county of Morgan and State of MlSSOllIl, have invented certain new and useful Improvements in Door Opening to the inner surface and Closing Devices, of which'the following is a specification.

My present invention relates generally to door opening and closing devices and more particularly to improvements in that especial type of door opening and closing device described and claimed in my 1,358,573 dated November 9, 1920;- the primary object of my present inv'entionbeing the provision of certain improvements upon the construction of mypatented device with respect to simplicity, strength, durability and general effectiveness.

In the accompanying drawing which illustrates my present invention and. forms a part of this specification, V

Figure 1 is a sectional top plan view illustrating the practical application of my invention,

Figure 2 is a doors open, I

Figure 3 is a top'plan view of my invention with the parts in the position shown in Figure 2, and

Figure 4: is a detail longitudinal section on an enlar ed scale, partially through the apparatus, s owing the latch.

Referring now to these figures and particularly to Figures 1, 2 and 3 I have shown in thefirst two of these figures a cabinet or other similar device 10 provided with horizontall'y swinging front doors 11 and 12, one thereof having a handle 13, and each provided with outer vertically disposed hinges 14. n My invention provides for the simultaneous opening of the doors 11 and. 12 when the handle 13 of the latter is drawn outwardly, as well as to hold the door stationary in the full open position and my invention also provides for the simultaneous closing of the doors upon release of a simple latch the latter of which becomes effective when the doors are fully opened.

To the above end my invention proposes a pair of door controlling arms 15 and 16, the former being rigidly attached as at 17 of the door 11 to extend at right angles to said door and the rigidity of which is insured by an angular brace 18 front elevation showing the Patenting this secured to the arm and to the door 11. as plainly seen in Figures 1 and 3. At its free end the door controlling arm 15 has a notch 19, and adjacent to its free end this arm supports a pivotal connection 20 between the same and the inner end of thedoor controlling arm 16'wl1ose outer end is pivotally connected as at 21 to a bracket 22 secured to the inner surface of the door 12 at or about a central point between its side edges. The arm 16 is in two parts 23 and 24: which may have longitudinal slots 25 and an adustable clamping bolt 26 through the slots so as to provide for lengthwise adjustment of the arm 16 over all to fit doors of various widths. It is obvious that various other mechanical expedients may be resorted to for the purpose of connecting the overlapping parts 23 and 24 of the arm 16 in adjustable relation.

Near its pivot 20 with the arm 15, the arm 16 has a pair of lengthwise spaced slots 27 and 28 through the former of which the downturned free end 29 of a latch piece 30 proyects so that when the doors 11- and 12 are swung to the openposition and the arms 15 and 16 swing therewith to lengthwise alined osition, the said downturned end 29 of the atch iece 30 may slip into the end notch 19 of t e arm 15. The-latch piece 30 is slidable on the inner rd of the arm 16 hown 1n Figures 1 and 2, whose inner end is anchored within the box or cabinet 10 and whose outer end is anchored to the inner surface of the door 12 adjacent to the hinged edge of the latter, and when it is desired to open the doors the handle 13 is grasped and the door 12 pulled toward open position. As this movement takes place the arm 16 swing ng outwardly pulls the door 11 open by vlrt-ue of its connection with the inner end of the arm 15 and when the doors durmovement shift to the fully open position shown inJF'igures 2 and 3, the latch piece 30 becomes engaged with the free end of the arm 15 so that the two arms 15 and 16 are thus locked in lon 'tudinally alined position so as to form in eflect a rigid brace across the space between the doors preventing thelatter from swinging inwardly to the closed the door actuating spring 34.

To release is obviously necessary to retract the latch iece against the tension of its controlling spring 33 and I have provided for this purpose a flexible releasing connection 35 secured at one end to the upstanding exten sion 32 of the latch iece and extending around and downwardly over guide ulleys 36 and 37, mounted on the inner sur ace of the door 12, the free end of this flexible connection depending below pulley 37 and having a terminal handle or weight 38. Thus a pul ulpon the handle or weight 38 has, throu feet 0 ulling the latch piece along t e arm 16 so'as to its downturned end 29 from the notch 19 of the arm 15. Immediately this takes place the two arms are free to flex with to one another and thus the doors 11 and 12 are simultaneously movable toward closed position under the tension-ofthe door actuatspring "84. Ehe connections and parts constituting present invention may thus be mounte position under the influence of the arms one from the other it the flexible connection-35, the efd 30 outwardly.

jacent to the up r i of the doors and w ll thus inte re to a inexpensive but are fectlve for the intended purposes.

I claim Controlling connections for oppositely swinging spring actuated doors, including an arm rigidly connected to, and pro'ecting inwardly at an an Is to, one of sai doors and having a flat end overlapping and pivotally connected to said first armat a point spaced from the free end of the latter and having its other end hingedly connected to the inner surface of" the other door whereby to constrain the oors to simultaneous opening and closin movemente, said rigid arm having a notch at its free end beyond said pivot, a spring controlled latch member longitudinally movable on the second arm adjacent to said pivot and shiftable into said notch 'when the two arms are longitudinally alined in the open position of the doors, a s controlling said latch member, and a s rin e releasing connection for said latch member extending adjacent to one of said doors.
